BATCH-WEIGHING DEVICE.

Application filed November 10, 1923, Serial No. 673,914. Renewed May 6, 1927.

This invention relates generally to auto matic batch Weighing devices.

The invention includes a charging receptacle mounted to receive material from a source of supply and to automatically shut oti the supply of material to the charging receptacle when a predetermined weight of material has been received therein. The invention further includes provision for causing the charging receptacle to automatically tilt to charging position when the predetermined weight of material constituting a charge has been received therein, and for manually locking the receptacle in charging position simultaneously with the opening of a valve permitting the charge to flow into the material-treating device with which the charging receptacle associated. l/Vhell the charge has been completely delivered the operator closes the discharge valve and in the same act releases the charge receptacle which thereupon automatically swings back to charge receiving position and in so doing automatically opens the supply valve to per mit material to again flow into the, charge receptacle from the source of supply.

in the drawings in which a preferred form of the invention has been selected for illustration,

Figure l isa view in side elevation of a charge weighing device embodying the illvention and showing the device in material recei vi ug position.

Figure 2 is a view similar to Figure 1 and showing the device in material delivering position.

Figure 3 is a view in front elevation of a supply valve with the cover removed.

Figure 4C is a view in vertical section of the valve device shown in Figure 3.

Figure 5 is a view similar to Figure 3 with one of the valve members removed.

Figure 6 is a View in front elevation and partly in section of a discharge valve used in the invention and showing the valve in closed condition.

Figure 7 is a view similar to Figure 6 showing the valve in'open position.

Referring to the drawings for a more detailed description of the invention, a charge receiving receptacle is shown at 10 and takes the form of a frusto-conical hollow drum having a considerably greater axial than diametrical dimension and mounted in a horizontal position on a pivoted support or cradle 11 placed nearer to the converging than the diverging end. With the construction and arrangement described it will be seen that the receptacle tends through its pivotal support to tilt downwardly at its overhung larger end. To oiiset this and to cause the receptacle to normally take a position tilted in the reverse direction, that is, with the larger end raised, a weight 12 is provided on a post 13 projecting from the smaller end of the receptacle. The Weight 12 causes the empty or partially filled receptacle 10 to normally take the position shown in Figure 1 of the drawing.

At 14: is shown a material supply pipe through which material passes from a source, not shown, into the charge receptacle lOby way of a valve chamber 15. The valve in they chamber 15 is operated by a valve arm 16 which is actuated by engagement with a socket or seat 17 carried by the receptacle, so that when the receptacle is in the position shown in Figure l the arm. 16 is swung to valve opening position. It will thus be seen that with the receptacle tilted by the action of the weight 12 as in Figure 1 the valve arm 16 ismanipulated to permit material to be received in the charge chamber.

\Vhen a quai'itity of material has been received in the charge receptacle sufficient to overbalance the weighted end, the receptacle tilts downwardly at the larger end and takes the position shown in Figure 2 of the drawing. in this position it will be seen that a discharge nozzle 18, with which the receptacle is provided, is lowered into a receiving hopper 19 leading directlyintothe device or apparatus 20 in which the material is treated.

The discharge nozzle 18 is provided with a valve chamber 21 in which a disk valve 22' cooperates with a discharge port 23. Operating means for the valve 22 include a pinion 24 and a rack 25 carried by aplunger 26 connected at one end to a handle member 27. The handle 27 is adapted to be swung about the pivotal point 28 to open or close the valve 22 and it will be seen that a latch member 29 with which the handle is provided engages with a catch lug 30 formed on the receiving hopper 19 when the valve is in open position as indicated in Figure 7 of the drawings.

It will be seen that with the structural arrangement described when the discharge valve is opened to deliver the contents of the charge receptacle into the treating device lll Elli

till

' lar position on the the charge receptacle is loclred in the dis charging position to insure that the Weight 12 will not return the charge receptacle to receiving position before the charge of material contained therein has been completely drained into the material-treating device.

lit will also be seen that-when the charge receptacle tilts to discharging position the valve arm 16 is moved to the left as in receptacle to receive the new charge through the receiving valve.

The receiving valve structure includes a tired valve plate ill and a rotatable valve plate 32. Per'liorations in the rotatable plate cooperate with corresponding perforations 3'? in the tired plate in the position of the valve arm 16 shown in Figure 1. A spring 34: holds the valve 32 to its seat and a set screw 35 is used to hold the cover plate 36 ot the valve chamber in place, Supplemental openings 38 in the valve plate serve to admit pressure between the valve and its seat and to facilitate the operation of the valve. The arm 16 may be adjusted in anguvalve rod and the socket member 17 which receives the end of the arm may also be adjusted to vary the opening or closing movement oi the valve arm. ,lt \vi ll be clear also that the weight of a charge or batch necessary to tilt the receptacle 10 can be varied, by adjustment of the weight 12 on the threaded post 13. The device shown and described may be used, tor eX- ample, in handling the mixture used. in noak ing ice cream,
